What is
Human Data?
Human Data is high-quality input created by domain experts. It's the kind of data that helps AI models understand context, nuance, and real-world complexity.
From labeling medical notes to evaluating legal outputs, expert-reviewed data makes the difference between a usable model and one that fails in production.
The Challenges of Training AI
AI models are only as good as the data they learn from.
Most training pipelines rely on large-scale data labeled quickly, often with little oversight or expertise.
The result? Models that misunderstand real-world inputs, hallucinate answers, or fail under edge cases.
Human-in-the-loop data solves this. By bringing trained experts into the labeling and review process, you ensure that your models learn from context-rich, accurate inputs.
